Hey Y'all I'm putting a 360 together for my dart and just doing basic bolt on upgrades. The problem is that I have four sets of heads all about in the same condition, so which set should I build? Just looking for best bang for buck.
Option 1: casting number 3671587 which says that they are either 73 340 or 73-74 360 or 76 360 heads with 1.88 1.60 valves.
Option 2:casting 2843675 which translates to 1968-74 273/318 heads with 1.78 1.50 valves.
Option 3: 3769974. 1975-76 360 heads with 1.88 1.60 valves.
Option 4: casting 4027596 is for 1980-84 but I've found differing info on these heads on valve size and application. So if someone could help sort through the bull that would be awesome.
So which would you use?
